My outbound email is being blocked. The message I am getting from my Mac Mail when trying to send a message from mail.bigpond.com is:
nschwcmgw08p Bigpond Outbound (OB105. Connection refused. 184.108.40.206 is listed on the Exploits Block List (XBL). Please visit http://spanhaus.org/xbl for more information.
I searched for the IP address and here is the search result - http://en.utrace.de/ip-address/220.127.116.11 and it appears Telstra's Brisbane server has been flagged by Spamhaus - http://www.spamhaus.org/faq/section/Spamhaus%20XBL#99
This has been an intermittent problem for a couple of days, but now it is happening all the time.
What's the best way to fix this?
